Whether you are bathing in water or simply listening to it rushing by, this natural element is always welcome in or near a nest. Immersing yourself in a body of water is the ultimate in protection and is a natural calming element that hearkens back to life in the womb. Surrounding water with plants and creating areas that feel safe and protected is a double whammy. Notice in this photo how the people are all standing in little carved out spaces under greenery, or surrounded by greenery, while still accessing the view of the water.
